Both dramas are linked to pet animals and mostly...cats
They are both fantasies where one of the leads can turn/shapeshift into cats
Both have strong ML
Fun to watch, lighthearted and sweet romances

Both FLs are special, the Love and redemption(God of war), Good and Evil(????)
Both FLs had past lives with the ML
Both shows had to unlock their own memories
Both are very worth watching, however Good and evil is slightly shorter with a different kind of ending

I would definitely recommend you to watch Good and evil if you like dramas that are xianxia like love and redemption

Both the FL accidentally entered and got trapped in a historical drama and ML was somewhat familiar to the FL(the idol Jing Qing - in The Queen of Attack ) & (the male lead of her series script - in The Romance of Tiger and Rose.
The FL's were both supposed to be a mere side character who is set to be killed by the ML.
The happy ending is set on the modern world.
The Romance of Tiger and Rose is longer with more episodes and plots but they are quite similar.

Both female leads are smart and strong and well genius
The male leads are both also smart
And if it counts both the female leads are by the same actress.
